Effect of herbaceous plant cultivation on soil fertility, rose growth and leaf photosynthetic characteristics in rose gardens

Soil management is an important task in the daily management and maintenance of plants, adopting scientific and reasonable soil management methods and soil improvement measures is of great significance in improving the growing environment of trees and promoting their growth and development. Herbaceous cultivation is a soil management method of planting grasses in the whole garden or between the rows of plants, and it has achieved good ecological and economic benefits in related practices. In order to explore the application effect of herbaceous cultivation in rose garden, and to provide a reference for guiding the ecological and scientific cultivation and management of roses, we proposed this study to carry out herbaceous cultivation experiments in the rose garden of the West Campus of Changjiang University in Jingzhou City. Alfalfa and clover were planted separately in the rose garden, with clean tillage as the control, and evaluating the soil water content, soil pH, alkaline dissolved nitrogen, effective phosphorus, quick-acting potassium content, and rose plant height, stem diameter, and photosynthetic gas exchange parameters of the rose plants after grassing in the soil layer of 0cm-30cm in each treatment area. The study showed that herbaceous cultivation affected soil nutrients and plant growth, and the correlation analysis revealed that there was a certain correlation between each soil fertility factor and rose growth and photosynthetic indexes under each herbaceous cultivation, and that the soil fertility factor had a closer relationship with plant photosynthetic characteristics. planting clover and alfalfa improved the fertility level of rose garden soil, effectively enhanced the growth of roses and the photosynthetic performance of leaves, and had a positive effect on soil improvement and sustainable production of rose garden.
